NIGHT-CLOCK.

SPECIFICATION' forming part of Letters Patent No. 339,220, dated April 6, 1886.

Application filed June i9, 1885.

fo {LZ/ 711710712/ if; may concern.-

le it known that l, CHARLES H. SHAW, of Brooklyn, in the county of Kings and State of New York, have invented a certain new and useful Improvement in Clocks, of which the following` is a specification.

The object of my improvement is to produce a simple, cheap, and neat clock, which will be convenient and effective for indicating time in a dark room.

ln my clock I use a train of time-register ing wheels, a platform rotated by the same once every twelve or twenty-four hours, a translucent globe or shade bearing opaque or semi-opaque figures or numbers carried by the platform, and a stationary hand orindex.

ln the accompanying drawings, Figure l is a sectional elevation of a clock embodying my improvement. Fig. 2 is a horizontal section ofthe same, taken at the plane of the dotted line a; x, Fig. l.

Similar letters of reference designate corre Spending parts in both iigures.

A designates a train of wheels for registering time. This train may be of any approved type. lt is arranged in a case, B, in such position that an arbor, a, which makes a rotation once every twelve hours, is vertical. The case L is shown as circular and tapering upwardly.

C designates a platforin,wl.1ich is supported on the arbor a. lt may be only frietiontight, or the said arbor may have only a frictiontight connection with a part from which it derives motion. This platform of course makes a complete rotation in every twelve hours.

On the platform C an illuminating deviceis Serial No. 170,054.

arranged. lt consists, as here shown, of a candle, D, fitted in a socket or candlestick, E. The outer edge of the platform C is upturned to'for'm a rim, c. A- globe or shade, G, made of translucent material, preferably opal. glass, is iitted upon the platform C, inside its rim c. It is carried by the platform,and hence makes a complete rotation once every twelve hours. As shown, it tapers upwardly; but it may be made of other shape. On it are delineated numbers indicative of the different hours of The globe is illuminated by the light inside it. The numbers will be delineated in opaque 0r semi-opaquematerial; hence they will be conspicuous and easily discerned.

On the ease B of the train of wheels A, a hand, J, is arranged. It is stationary, and extends upward into the range of the numbers upon the globe. The position of the numbers on the globe with .relation to the hand indicates the time.

.Vhat I claim as my invention, and desire to secure by Letters Patent, is-

In a clock, the combination of a train of time-registering wheels arranged in such position that the hour shaft or arbor is vertical, a platform carried by said hour shaft or arbor, a translucent globe or shade arranged on the platform and marked with numbers in opaque or semi-opaque material, au illumi- Dating device inside the globe or shade, and a stationary hand, substantially as specified.
